QGC's compiling errors with MAC

Hello,
I compile QGC(master) with QT at macOS big sur(v11.5.2). It encounters errors although I don’t change anything about the code. Meanwhile I install QT just as the instruction step by step. What is the problem? How could I fix it? Thank you!
part of qt’s output.:
